Thanks for the reply.

I want to find Friction Factor in Solidworks Flow Simulation.

I have pipe diameter 1 inch with inlet velocity 30 ft/s.

And the material is Ductile iron.

Even if there is a way to find reynolds number for above parameters?I can then use equation goals to find friction factor.

Any help would be greatly appreciated.

ThanksYou will need to input a surface roughness for your pipe. The software will then use some empirical formula (likely the same Moody chart) to estimate the friction factor. You would be better off just referencing the chart and forgoing simulation entirely, this doesn't seem like a problem well suited for simulation.

Use a wall boundary condition on the inside surface of your pipe (or set the default roughness in the initial conditions for all surfaces). There you can specify the roughness of your pipe walls.

Please check the link. If it's acceptable or not.

I've drtectly put equation goals having kinematic viscosity eta for reynolds number calculation and for roughness epsilon value has been directly put in there.If there's a better way to do it.

Your roughness goal is meaningless, the software cannot calculate your roughness based on a simple cylindrical CAD part.

**You**need to provide this data**to the software**, right here in the wall boundary condition:I still don't think this is a problem that requires simulation. Just calculate your Reynold's number based on the pipe diameter and the fluid average velocity, then use the Moody chart to figure out your friction factor.
